ICE AIR CONDITIONING SYSTEM Filed April 5, 1945 INVBVTOR. John M. Hall Patented Oct. 1, 1946 "UNITED AT ES PATENT, OFFICE roam-R.- GGNDITIONING SYSTEM I v I res-n M. iiaii, New York. N. Y1 I ap ueationnprn 5,1945,- Serial No: 586,664

This invention relates to new and useful improvements in anair conditioning. system.

More particularly the new and improved air conditioning. system is characterized by a box-like housing having an air inlet and an air discharge.

which an extensionconduit' is connected with the housing so that other rooms may also be cooled. A novel arrangement urbane plates'for guiding the air against the cake of" ice,-. is also proposed.

Still further the in'vention'proposes the; construction of an air conditioning-system, as briefly mentioned which is exceptionally simple, contains no complicated machinery, which is desir able, and which may be manufactured and sold ata reasonable cost; h h

For further comprehension of the invention, and of the objects and advantages thereof,- reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which the Various novel-featuresof the invention are more particularly set forth;

In the'accompanying drawing forming a ma terial part-of this disclosure Fig. 1 is a perspecti e view of an air conditioning' system constructed in accordance with this invention.

The new and improved air condition-ingsystem, in accordance with this invention includes'a boxlike housing IO having an air inlet :1 and anair discharge I2. The housing HT is substantially of L-shape in=1ongitudina1 vertical section. It-is provided with a vertical portion I4 which connects with'a horizontal port-ion l5. Th vertical.

portion M ispr ovided with a hollow top head I6 having lou-vered openings comprising said air in-'' let M. An electric fan I] is mounted-inthis head portion IB and is capable of blowing airthrough the housing i0. The-discharge ["2 is in the nature of perforations and openings, in the topof the horizontal section l-5-.-

A support l8 fora cake of ice i9 is arranged within the horizontal portion It; This support" it is of open worksothat water from the ice may drainoff. .7 A=drain-pipe is mounted in the bottom wall of the horizontal portion 1-5 and discharges into a tray 2i which isremovably mounted ina space ZZ'formed in the bottom wallof the housing Hi. The opening 22 is closedw-ith -a redischarge movable cover 23,

The electrician l'i-is provided with a starting rheostat I'l for controllingthe motor speed. by avariable resistor. By means of this rheostatthe air pressure may beincreasedor decreased by anyone.

The housing Ill provided witha door built upon oneside-thereof. This door is normally held'closed'with a latch 2-6.- 'Whenthe door 2-5 is opened it ispossible to reach the ice cake sup port it so that a'cake of ice-may be placed upon the support It}:

The operation of the air conditioning system may be understood fromthe following.-

Whenthe'electric fan 11- operates-it will blowa: draftof airth-rough the housing It. The air will enter through: the louvered air inlet I I. The stream of airwill-strikathe cake of ice i9,--and flow around the cake, and finally discharge through the air discharge t2; The discharged air will be cooL-b'eca-usethe ice will" absorb heat out of the air, initspassage through the hous- In Figs. 4 to 9 inclusive; a modified form of thGiiIIVBIltlOII has been disclosed which is very similar to-t'he; prior-form distinguishing in seve In this form of the invention the:

eral ways. housing 10 is providedwith an end extension conduit 28 which, in turn, is provided with an air 29. Preferably this extension conduit 28 is connected with the end of the horizontal section l5 of the housing l3. The end of the housing is formed with additional perforations l2 or any other form of air discharge, so the air from the housing l may enter the extension conduit 28 and be discharged from the discharge 29. The extension conduit 28 may be extended to a different room or other quarters and may be attached to any part of the horizontal portion l of the housing H3, in Fig. 1 or Fig. 4.

The housing I3 is also provided with a group of baflle plates, and means for holding said plates in various positions so as to direct the stream of air against the ice cake in various ways. More specifically, there is a top pair of baffle plates 30,-

3| and a similar bottom pair of bafile plates 30, 3|. The bafile plates 33, 3| are connected with each other by hinge ears 32. The rear ends of the baffle plates 39 are formed with hooked portions similar to the hinge cars 32 which engage around support rods 34, which have their ends slidably engaged in horizontal slots 35 formed in the side Walls of the housing It. With this arrangement the rear ends of the baflle plates 30 are capable of sliding, and pivoting.

The front ends of the baffle plates 3i are formed with hooked portions 38 which are engaged about rods 39 supported upon racks 43. The racks 4B are slidably mounted through brackets 4| which are mounted on shafts 42. These shafts 42 are provided with gears 43 meshing with-the racks 40. The shafts 42 are rotatively mounted upon the side walls of the housing It], and project through one of said side walls. The projecting ends of the shafts 40 are provided with arms 44 equipped with set screws 45, or other holding element by which the arms 44 may be locked in various turned positions so as to lock the gears 43 correspondingly.

The hinges 32 of the baflie plates 30 and 3| are supported by cables 48 which are engaged over drums 49 mounted on shafts 50 rotatively supported across the side walls of the housing |0. One of the end of each of the shafts 53 extend through one of the walls of the housing l0. These outer ends are provided with arms 5| equipped with clamping screws 45 by which they may be held in various turned positions.

The baflle plates 30 and 3| may be arranged to direct air against the cake of ice, in various ways. The hinge portions 32 of the battl -plates 30 and 3| may be moved towards each other, or away from each other so as to close the throat opening between the bafile plates 30. To do this, the arms 5| are freed, and then turned, so as to turn the shafts 50 and they drums 49 to let out, or draw in, the cables 48, as desired.

The front ends of the baffle plates 3| may be moved towards each other, or away from each other, or may be raised, or lowered to various positions by freeing the arm 44 and turning said arms to turn the shafts 42 indirectly raise, or lower the racks 49 which in turn raise, or lower the front ends of the baffle plates 3|.

In other respects this form of the invention is identical to the prior form and like parts may be recognized by the same reference numerals.

The operation of the second form of the invention is identical to the first form except for the fact that the stream of air blown against the cake of ice may be controlled by controlling the baflie plates 30 and 3|.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim a new, and desire to secure "by United States Letters Patent is:
